Tŷ Gwyrddfai Decarbonisation Hub

The first decarbonisation hub of its kind is being established in Penygroes. 

The development, called Tŷ Gwyrddfai is a collaborative project between Adra, Busnes@LlandrilloMenai and Bangor University and will transform the industrial site into a decarbonisation hub that will ensure that north west Wales will be at the forefront of the decarbonisation agenda, working with communities and businesses to retrofit homes over the next 10 years

  • The site’s history

    From this site Northwood Hygiene Products operated a hygiene materials manufacturing company, employing up to 100 workers. The site closed in October 2020.  

    After discussions with Welcome Furniture, this site was leased by Adra, with the intention of creating a training centre for displaying and installing products that would be part of the process of decarbonising homes owned by Adra.  

    The site also includes the Travis Perkins depot which provides Adra and its contractors with equipment for the repair and refurbishment of existing housing stock and the construction of new housing. 

  • The name

    The name Gwyrddfai is a play on the words Gwyrdd and Gwyrfai.

    The “gwyrdd” translates to green which is a significant symbol for the environment and conveys what Adra and partners are hoping to achieve through decarbonisation. “Tŷ” translates to house and is at Adra’s core and roots as a company and housing provider.

    A shortlist of names were presented to pupils at Ysgol Dyffryn Nantlle, Penygroes from staff at Adra.

  • The benefits

    In the longer term, the development will lead to a more qualified and skilled workforce, which will support the local construction sector and ensure that any value generated through decarbonisation and related capital investment will be retained locally.  

    It will also contribute towards reducing carbon emissions in our homes, which in turn will reduce the impact of increasing fuel and energy costs by making our homes more energy efficient and improve the quality of life for our tenants. 

    There is genuine excitement among the partners and in the region about this project and the social value and positive difference it can achieve to local communities and the local economy.
